The Internet giveth...and the Internet taketh away.
It seems that when we transferred our domain name to our new host, weebly.com, our email address went kaput. As a result, we're not able to send emails out from email@example.com, and we aren't able to receive them either.
Take heart, as our contact form still works. Until we can resolve this issue, I'll be forwarding any contact form messages to my work address and answering them from there. Unfortunately, I still have a batch of unanswered messages from the old site that I still need to get to. I'll answer them all as quickly as I can.
